In the following description, for purposes ofexplanation, numerous specific details are set forth in order to providea thorough understanding of the various embodiments. It is evident,however, that the various embodiments can be practiced without thesespecific details (and without applying to any particular networkedenvironment or standard).

As used in this disclosure, in some embodiments, the terms “component,”“system” and the like are intended to refer to, or comprise, acomputer-related entity or an entity related to an operational apparatuswith one or more specific functionalities, wherein the entity can beeither hardware, a combination of hardware and software, software, orsoftware in execution. As an example, a component may be, but is notlimited to being, a process running on a processor, a processor, anobject, an executable, a thread of execution, computer-executableinstructions, a program, and/or a computer. By way of illustration andnot limitation, both an application running on a server and the servercan be a component.

One or more components may reside within a process and/or thread ofexecution and a component may be localized on one computer and/ordistributed between two or more computers. In addition, these componentscan execute from various computer readable media having various datastructures stored thereon.

Asanother example, a component can be an apparatus with specificfunctionality provided by mechanical parts operated by electric orelectronic circuitry, which is operated by a software application orfirmware application executed by a processor, wherein the processor canbe internal or external to the apparatus and executes at least a part ofthe software or firmware application. As yet another example, acomponent can be an apparatus that provides specific functionalitythrough electronic components without mechanical parts, the electroniccomponents can comprise a processor therein to execute software orfirmware that confers at least in part the functionality of theelectronic components. While various components have been illustrated asseparate components, it will be appreciated that multiple components canbe implemented as a single component, or a single component can beimplemented as multiple components, without departing from exampleembodiments.

Embodiments described herein can be exploited in substantially anywireless communication technology, comprising, but not limited to,wireless fidelity (Wi-Fi), global system for mobile communications(GSM), universal mobile telecommunications system (UMTS), worldwideinteroperability for microwave access (WiMAX), enhanced general packetradio service (enhanced GPRS), third generation partnership project(3GPP) long term evolution (LTE), third generation partnership project 2(3GPP2) ultra mobile broadband (UMB), high speed packet access (HSPA),Z-Wave, Zigbee and other 802.XX wireless technologies and/or legacytelecommunication technologies.

In traditional LTE Physical Downlink Shared Channel (PDSCH) RE mappingsignaling, the LTE PDSCH resource element (RE) mapping scheme wasdesigned to map around known signals and other channels.Correspondingly, the signaling was designed to indicate theconfigurations of those RS/channel so the mobile device can implicitlyknow the RE locations (e.g., the RE mapping pattern for a givenparameter set is implicitly derived from the following parameters:crs-PortsCount-r11; crs-FreqShift-r11; mbsfn-SubframeConfigList-r11;csi-RS-ConfigZPId-r11; pdsch-Start-r11; qcl-CSI-RS-ConfigNZPId-r11; andzeroTxPowerCSI-RS2-r12.

It is foreseen that 5G can benefit from being optimized to fit a varietyof traffic and services. Therefore, the first released NR should ideallybe “future compatible”. Forward compatibility can be facilitated byhaving the first released version of NR co-exist with future servicesefficiently. That is the motivation to introduce reserved resource inNR.

In general, a reserved resource is a high layer configured resource forthe mobile device to avoid transmission and/or reception within. In thefuture, some new services are introduced in NR where some RS or dataresource need to be introduced. In this case, the network can simplyconfigure them as reserved resource to legacy mobile devices to avoidsevere impact to those legacy mobile devices.

As the reserved resource is designed for future services, the LTE typeof RE mapping signaling is not enough since the future RS is not knownnow. Therefore, the signaling must be flexible. However, some systemsmay disadvantageously utilize large signaling overhead, for each mobiledevice. For example, in some cases, per RE bitmap requires 12*14=168bits for signaling.

New Radio (NR) will allow for semi-statically and/or reserved resourcesin both time and frequency domain to overcome the aforementionedshortcomings of LTE. One or more embodiments described herein canprovide for approaches to configure reserved resources.

Systems, methods and/or machine-readable storage media for facilitatingcompact signaling via a multi-dimensional bitmap in a 5G wirelesscommunication system are provided herein. One or more embodimentsdescribed herein can provide a compact signaling design for a reservedresource. For example, a multi-dimensional (e.g., two-dimensional)bitmap can be used as signaling to configure reserved resources in thegranularity of one resource element (RE). The two-dimensional bitmap isconstructed by overlaying two bitmaps separately (a first bitmap in thetime domain and a second bitmap in the frequency domain).

Legacy wireless systems such as LTE, Long-Term Evolution Advanced(LTE-A), High Speed Packet Access (HSPA) etc. can have downlink controlchannels that carry information about the scheduling grants. Typicallythis includes a number of multiple input multiple output (MIMO) layersscheduled, transport block sizes, modulation for each codeword,parameters related to hybrid automatic repeat request (HARQ), subbandlocations and also precoding matrix index corresponding to the subbands.

Typically, the following information can be transmitted based on thedownlink control information (DCI) format: Localized/Distributed virtualresource block (VRB) assignment flag, resource block assignment,modulation and coding scheme, HARQ process number, new data indicator,redundancy version, transmit power control (TPC) command for uplinkcontrol channel, downlink assignment index, precoding matrix indexand/or number of layers.

As used herein, “5G” can also be referred to as New Radio (NR) access.Accordingly, systems, methods and/or machine-readable storage media forfacilitating RE mapping for efficient use of the downlink controlchannel in a 5G wireless communication system are desired. As usedherein, one or more aspects of a 5G network can comprise, but is notlimited to, data rates of several tens of megabits per second (Mbps)supported for tens of thousands of users; at least one gigabit persecond (Gbps) to be offered simultaneously to tens of users (e.g., tensof workers on the same office floor); several hundreds of thousands ofsimultaneous connections supported for massive sensor deployments;spectral efficiency significantly enhanced compared to 4G; improvementin coverage relative to 4G; signaling efficiency enhanced compared to4G; and/or latency significantly reduced compared to LTE.

One or more embodiments described herein can include systems, apparatus,methods and/or machine-readable storage media that can facilitatecompact signaling via a multi-dimensional bitmap in a 5G wirelesscommunication system are provided herein. In one embodiment, anapparatus is provided. The apparatus can comprise: a processor; and amemory that stores executable instructions that, when executed by theprocessor, facilitate performance of operations. The operations cancomprise: determining a multi-dimensional bitmap in a time domain and afrequency domain, wherein the time domain is represented by anorthogonal frequency division multiplexed symbol and the frequencydomain is represented by an orthogonal frequency division multiplexedsubcarrier. The determining comprises: selecting a group of reservedresource allocations of the multi-dimensional bitmap in which datainformation is not to be communicated; assigning, to the group ofreserved resource allocations, a first value for the orthogonalfrequency division multiplexed symbol of the multi-dimensional bitmapand the orthogonal frequency division multiplexed subcarrier of themulti-dimensional bitmap according to a location of elements of thegroup of reserved resource allocations; and assigning, to other portionsof the multi-dimensional bitmap other than the group of reservedresource allocations, a second value distinct from the first value. Theoperations further comprise transmitting the multi-dimensional bitmap toa mobile device.

In another embodiment, a method is provided. The method comprisesdetermining, by a device comprising a processor, a multi-dimensionalbitmap in a time domain and a frequency domain, wherein the time domainis represented by an orthogonal frequency division multiplexed symboland the frequency domain is represented by an orthogonal frequencydivision multiplexed subcarrier. The determining comprises: selecting agroup of reserved resource allocations of the multi-dimensional bitmapin which data information is not to be communicated; assigning, to thegroup of reserved resource allocations, a first value for the orthogonalfrequency division multiplexed symbol of the multi-dimensional bitmapand the orthogonal frequency division multiplexed subcarrier of themulti-dimensional bitmap according to a location of elements of thegroup of reserved resource allocations; and assigning, to other portionsof the multi-dimensional bitmap other than the group of reservedresource allocations, a second value distinct from the first value. Themethod further comprises facilitating, by the device, transmitting themulti-dimensional bitmap to a mobile device.

In yet another embodiment, a machine-readable storage medium, comprisingexecutable instructions that, when executed by a processor of anapparatus, facilitate performance of operations is provided. Theoperation comprise: receiving a multi-dimensional bitmap associated withorthogonal frequency division multiplexed symbols and orthogonalfrequency division multiplexed subcarriers, wherein themulti-dimensional bitmap comprises: reserved resource allocations viawhich signaling information is to be communicated by the apparatus to amobile device that receives the multi-dimensional bitmap and via whichdata information is not to be communicated from the apparatus, whereinthe reserved resource allocations comprise a first value for selectedones of the orthogonal frequency division multiplexed symbols of themulti-dimensional bitmap and the orthogonal frequency divisionmultiplexed subcarrier of the multi-dimensional bitmap. The operationsfurther comprise receiving signaling information according to thereserved resource allocations of the multi-dimensional bitmap from themobile device.

One or more embodiments can flexibly allow a two-dimensional bitmapsignaling framework to support per RE level granularity. In addition,such two-dimensional bitmap will result in a symmetric pattern. Forasymmetric RS design, this signaling framework may include someunnecessary REs; however, it is foreseen that the resource used forfuture service is most likely to be symmetric design. Additionally, oneor more embodiments can have low overhead in comparison of 168 bitssignaling overhead per mobile device, this solution only needs 12+14=26bits for the signaling overhead per mobile device.

FIG. 1 illustrates an example, non-limiting message sequence flow chartto facilitate compact signaling design for reserved resourceconfiguration via a multi-dimensional bitmap in accordance with one ormore embodiments described herein. FIG. 2 illustrates an example,non-limiting block diagram of a base station device that can facilitatecompact signaling design for reserved resource configuration viamulti-dimensional bitmap in accordance with one or more embodimentsdescribed herein. FIG. 3 illustrates an example, non-limiting blockdiagram of a mobile device for which compact signaling design forreserved resource configuration via a multi-dimensional bitmap can befacilitated in accordance with one or more embodiments described herein.FIG. 4 illustrates an example, non-limiting multi-dimensional bitmapthat can be employed to facilitate compact signaling design for reservedresource configuration in accordance with one or more embodimentsdescribed herein. Repetitive description of like elements employed inother embodiments described herein is omitted for sake of brevity.

The system 100 described herein can provide for a compact signalingdesign for the reserved resource via use of a multi-dimension (e.g.,two-dimension) bitmap as signaling to configure reserved resource in thegranularity of one RE. The two-dimensional bitmap is constructed by twobitmaps: in time and frequency domain separately.

One or more embodiments can enable the BS device 102 to dynamicallysignal the mobile device 104 to use specific REs located at particularOFDM symbol/OFDM subcarrier pairs in some embodiments as shown in FIG. 4for signaling, for example. As used herein, dynamically signaling canmean signaling of information that can change from time to time.

In some embodiments described herein, the BS device 102 can transmitinformation to the mobile device 104 configuring resource reservationvia a multi-dimensional mapping pattern. In one or more of the variousembodiments described herein, this new signaling framework uses twobitmaps to construct the reserved resources, which is of much lowersignaling overhead compared to a per RE level bitmap.

Turning back to FIG. 1, one or more of reference signals and/or pilotsignals can be transmitted as shown at 108 of FIG. 1. The referencesignals and/or the pilot signals can be beamformed or non-beamformed.The mobile device 104 can compute the channel estimates then determinethe one or more parameters associated with channel state information(CSI) reporting. The CSI report can comprise example channel qualityindicator (CQI), preceding matrix index (PMI), rank information (RI),the best subband indices, best beam indices etc. or any number of othertypes of information.

The CSI report can be sent from the mobile device 104 to the BS devicevia a feedback channel (e.g., feedback channel 110). The BS device 102scheduler can use this information in choosing the parameters forscheduling of the particular mobile device 104. As used herein, the term“BS device 102” can be interchangeable with (or include) a network, anetwork controller or any number of other network components. The mobiledevice 104 can send the scheduling parameters to the mobile device 104in the downlink control channel (e.g., downlink control channel 112).After this information is transmitted, the actual data transfer can beprovided from the BS device 102 to the mobile device 104 over the datatraffic channel 114.

The downlink control channel can carry information about the schedulinggrants. As previously discussed, typically this includes a number ofmultiple input multiple output (MIMO) layers scheduled, transport blocksizes, modulation for each codeword, parameters related to hybridautomatic repeat request (HARQ), subband locations and also precodingmatrix index corresponding to the sub bands. Additionally, typically,the following information can be transmitted based on the downlinkcontrol information (DCI) format: Localized/Distributed virtual resourceblock (VRB) assignment flag, resource block assignment, modulation andcoding scheme, HARQ process number, new data indicator, redundancyversion, transmit power control (TPC) command for uplink controlchannel, downlink assignment index, precoding matrix index and/or numberof layers.

In some embodiments, as described in more detail with reference to FIGS.2, 3 and 4, the downlink control channel can also carry data in one ormore subcarriers of an OFDM control channel symbol at specific OFDMsubcarriers to improve efficiency of the control channel.

Turning to FIG. 2, the base station device 102 can comprise acommunication component 202, a bitmap determination component 204,memory 206 and/or processor 208. In some embodiments, the communicationcomponent 202, a bitmap determination component 204, memory 206 and/orprocessor 208 can be electrically and/or communicatively coupled to oneanother to perform one or more functions of the base station device.

Turning to FIG. 3, the mobile device 104 can comprise communicationcomponent 302, resource reservation component 304, mobile deviceevaluation component 306, rate matching component 308, memory 310 and/orprocessor 312. In some embodiments, one or more of communicationcomponent 302, resource reservation component 304, mobile deviceevaluation component 306, rate matching component 308, memory 310 and/orprocessor 312 can be electrically and/or communicatively coupled to oneanother to perform one or more functions of the mobile device 104.

With reference to FIGS. 2, 3 and 4, the bitmap determination component204 of the base station device 102 can construct the multi-dimensional(e.g., two-dimensional) bitmap of FIG. 4 from two separate bitmaps. Thetwo separate bitmaps can be a first bitmap associated with time andcorresponding to OFDM symbol locations, and a second bitmap associatedwith frequency and corresponding to OFDM subcarrier locations. As shownin FIG. 4, the OFDM symbol location axis can be placed along a firstaxis and the OFDM subcarrier location axis can be placed along a secondaxis.

In constructing the multi-dimensional bitmap, for example, the bitmapdetermination component 204 can construct Bitmap-1 of FIG. 4 as X_(l)where l is the index of OFDM symbol, and construct Bitmap-2 as Y_(k)where k is the index of OFDM subcarrier. The final reserved resourcemapping can be defined by the bitmap determination component 204 b asr_(k,l)=0.

The bitmap determination component 204 can construct themulti-dimensional bitmap by overlaying the contents of the Bitmap-1 andBitmap-2 as shown in FIG. 4. One RE corresponds to one OFDM symbol intime domain and one subcarrier/tone in frequency domain.

The bitmap determination component 204 can determine, for each ofBitmap-1 and Bitmap-2, which REs will have a value of “0” (meaning themobile device can use the resource for data) or a value of “1” (meaningthe resource is only to be used for signaling). As shown, the REs 404that have a value of “1” for the OFDM symbol location and for the OFDMsubcarrier location can be employed for signaling. Other REs (e.g., RE402) can be employed for data.

Thus, the two bitmaps can cover a two-dimensional area. The bitmapdetermination component 204 can generate and/or determine the portionsof the bitmap corresponding to REs 404. The portions of the bitmapcorresponding to REs 404 are not to be used for PDCH transmission (thedata is sent only to the other areas (e.g., REs 402). The signalinginformation is therefore limited to REs 404, which are the REs where thevalue of the OFDM symbol location and the value of the OFDM subcarrierare both assigned to value “1” by the bit determination component 202.While REs 404 are indicated by value “1” in some embodiments, they couldbe indicated by the REs where the value of the OFDM symbol location andthe value of the OFDM subcarrier are both assigned to value “0” by thebit determination component 202 (while the other REs 402 are indicatedby value “1”). All such embodiments are envisaged.

The mobile device evaluation component 306 can receive and/or transmitsignaling information at REs 404 while receiving and/or transmittingdata at REs 402. The rate matching component 308 can determine that, forthe multi-dimensional bitmap (e.g., the multi-dimensional bitmap of FIG.4), altogether, there are 168 REs with 16 of those REs being REs 404(and that are therefore reserved for signaling). Accordingly, the ratematching component 308 can determine that the total available resourcefor data transmission and/or reception becomes 168−16=152 bits. As such,when the rate matching component 308 performs rate matching this means adecoder of the mobile device 104 can use different decoding rates tomatch the 152 bits. The two-dimensional bitmap of FIG. 4 can be employedby the rate matching component 308 and/or the decoder of the mobiledevice 104 as the input to the decoder to tell the decoder the decodingrate.

Accordingly, (k,l)∈{(k,l)|X_(l)*Y_(k)=1}, where X_(l), Y_(k) are RRCsignalling configured bitmaps configured by the bitmap determinationcomponent 202. As shown in FIG. 4, Bitmap-1 and Bitmap-2 are high layerconfigured bitmaps, and the reserved resource is defined according toboth bitmaps. For a particular RE, the corresponding OFDM subcarrier andOFDM symbol index can map this RE to both bitmaps. If the bit in bothbitmaps is 1, then the RE is considered as reserved resource.

The communication component 202 of the base station device 102 cantransmit the multi-dimensional bitmap to the communication component 302of the mobile device 104. The resource reservation component 304 of themobile device 104 can determine the content of the multi-dimensionalbitmap and the mobile device evaluation component 306 can determinewhether to transmit and/or receive data and/or signaling based on thedetermination of the multi-dimensional bitmap made by the resourcereservation component 304.

In some embodiments, any number of different arrangements of REs havingvalues of “1” and “0” can be configured by the bitmap determinationcomponent 202 (and thus, the values at particular, OFDM symbol locationsand OFDM subcarriers can be different than that shown in FIG. 4). Thus,the locations of REs 404 can differ in different embodiments.

In some embodiments, the bitmap determination component 202 can designthe multi-dimensional bitmap such that there is symmetry design for REs(e.g., the REs 404 are symmetric with one another across the OFDM symbollocations and OFDM subcarriers).

The memory 206 can be a computer-readable storage medium storingcomputer-executable instructions and/or information configured toperform one or more of the functions described herein with reference tothe base station device 102. For example, in some embodiments, thememory 206 can store computer-readable storage media associated withdetermining one or more bitmaps and/or the multi-dimensional bitmap. Theprocessor 208 can perform one or more of the functions described hereinwith reference to the base station device 102.

The memory 310 can be a computer-readable storage medium storingcomputer-executable instructions and/or information configured toperform one or more of the functions described herein with reference tothe mobile device 104. For example, in some embodiments, the memory 310can store computer-readable storage media associated with determiningthe value of one or more REs of a multi-dimensional bitmap, determiningwhether to transmit and/or receive, performing rate matching etc. Theprocessor 312 can perform one or more of the functions described hereinwith reference to the mobile device 104.

At 804, method 800 can comprise receivingsignaling information according to the reserved resource allocations ofthe multi-dimensional bitmap from the mobile device. In someembodiments, the multi-dimensional bitmap comprises a two-dimensionalbitmap.

The logical connections depicted comprisewired/wireless connectivity to a local area network (LAN) 1252 and/orlarger networks, e.g., a wide area network (WAN) 1254. Such LAN and WANnetworking environments are commonplace in offices and companies, andfacilitate enterprise-wide computer networks, such as intranets, all ofwhich can connect to a global communications network, e.g., theInternet.

When used in a LAN networking environment, the computer 1202 can beconnected to the local network 1252 through a wired and/or wirelesscommunication network interface or adapter 1256.

Thus, thecommunication can be a defined structure as with a conventional networkor simply an ad hoc communication between at least two devices.

Wi-Fi can allow connection to the Internet from a couch at home, a bedin a hotel room or a conference room at work, without wires. Wi-Fi is awireless technology similar to that used in a cell phone that enablessuch devices, e.g., computers, to send and receive data indoors and out;anywhere within the range of a femto cell device. Wi-Fi networks useradio technologies called IEEE 802.11 (a, b, g, n, etc.) to providesecure, reliable, fast wireless connectivity. A Wi-Fi network can beused to connect computers to each other, to the Internet, and to wirednetworks (which can use IEEE 802.3 or Ethernet). Wi-Fi networks operatein the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11a) or54 Mbps (802.11b) data rate, for example or with products that containboth bands (dual band), so the networks can provide real-worldperformance similar to the basic 12 Base T wired Ethernet networks usedin many offices.

The embodiments described herein can employ artificial intelligence (AI)to facilitate automating one or more features described herein. Theembodiments (e.g., in connection with automatically identifying acquiredcell sites that provide a maximum value/benefit after addition to anexisting communication network) can employ various AI-based schemes forcarrying out various embodiments thereof. Moreover, the classifier canbe employed to determine a ranking or priority of each cell site of anacquired network. A classifier is a function that maps an inputattribute vector, x=(x1, x2, x3, x4, . . . , xn), to a confidence thatthe input belongs to a class, that is, f(x)=confidence(class). Suchclassification can employ a probabilistic and/or statistical-basedanalysis (e.g., factoring into the analysis utilities and costs) toprognose or infer an action that a communication device desires to beautomatically performed. A support vector machine (SVM) is an example ofa classifier that can be employed. The SVM operates by finding ahypersurface in the space of possible inputs, which the hypersurfaceattempts to split the triggering criteria from the non-triggeringevents. Intuitively, this makes the classification correct for testingdata that is near, but not identical to training data. Other directedand undirected model classification approaches comprise, e.g., naïveBayes, Bayesian networks, decision trees, neural networks, fuzzy logicmodels, and probabilistic classification models providing differentpatterns of independence can be employed. Classification as used hereinalso is inclusive of statistical regression that is utilized to developmodels of priority.

As will be readily appreciated, one or more of the embodiments canemploy classifiers that are explicitly trained (e.g., via a generictraining data) as well as implicitly trained (e.g., via observingcommunication device behavior, operator preferences, historicalinformation, receiving extrinsic information). For example, SVMs can beconfigured via a learning or training phase within a classifierconstructor and feature selection module. Thus, the classifier(s) can beused to automatically learn and perform a number of functions,comprising but not limited to determining according to a predeterminedcriteria which of the acquired cell sites will benefit a maximum numberof subscribers and/or which of the acquired cell sites will add minimumvalue to the existing communication network coverage, etc.
